LINOTYPE-MACHIN'E.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed July 21, 1917. Serial No. 182,033.

To all whom it may concern:

Be it known that I, ARTHUR O. MGGRATH, a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented new an useful Improvements in Linotype-Machines, of which the following is a full, clear, conclilseii to the accompanying drawing, formmg a part of this specification.

My invention relates to improvements in linotype machines and has for one of its particular objects the provision of means whereby stereotypes may be cast directly from a linotype machine, the present application being a continuation of my a plication filed October 14, 1916, Serial 0. 125,610, as to so much of the subject-matter as was disclosed in said application.

Heretofore it has been customary in setting up advertisements and the like, where stereotypes are used for insertion in the advertisement, particularly for the purpose of illustration, etc., to make these stereotypes by a separate apparatus. This requires considerable time and additional labor in a printing office, and it is one of the objects of my present invention to provide means whereby such stereotypes may be cast di-' rectly from the linotype machine by a simple mechanism which may be used on the linotype machine connecting the parts thereof or without disarranging the working parts of the linotype machine.

For the purpose of disclosing my invention, I have illustrated in the accompanying drawings certain embodiments thereof. In said drawings- Figure 1 is a vertical section through the mold disk and adjacent parts of a linotype machine, showing the mold in position to cooperate with my stereotype mold;

Fig. 2 is a perspective view of the stereotype mold box adapted to be used in connection with the linotype machine;

Fig. 3 is a vertical sectional view of the box shown in Fig. 2;

Fig. 4 is a erspcctive view of one of the interchangeable liners in the box;

without in any way dis-.

the machine is provided, as usual, with the slotted mold 2, in which the linotype slugs, as a rule, are cast. This mold is carried by the rotatable mold-carrying disk 3, which, when the casting operation takes place, brings the mold 2 into position 0 posite the nozzle 4 of the metal pot 5. T e matrix support 6 of the machine is of the usual construction, being provided with a transversely extending slot 7 in which the matrices are adapted to fit, and this slot, as is shown, is provided on one interior face with a rib interior face with a rib 9. The purpose of these ribs will appear more fully herein after, as will also appear the purpose of the jib 10 on the bottom of the mold 2. The matrix-holder 6 is mounted on the transversely extending arm 11 of the elevator, the vertically extending arm 12 of which is slidably mounted on the frame 1 and is raised and lowered by the lever 13 pivoted at 14 and being raised into raised position by means of a cam 16 operating upon a roller 17 mounted upon the lever 13.

Fitting in the matrix-holder 6 is a stereotype casting box 18, which preferably takes the form illustrated in Figs. 2 to 4. The casting box illustrated in these figures comprises a pair of plates 19 and 20, one of which at its .bottom is provided with an angle flange or bar 21 to which the other plate 19 is hinged, as at 22. These plates are formed of metal and are of such dimensions that in cross-section they approximate the outlines of the standard linotype, matrix. The plate 20 is provided at its top with a pair of oppositely disposed ribs 23 and 24, and intermediate of its top and bot tom, at a point nearer the top than the bottom, the plates 19 and 20 are provided with ribs 25 and 26 respectively. These ribs act as guides in supporting the box in positlon, as will be apparent from examination of Fig. 1. The ribs 23 and 24, when the box 1s slid into the matrix-holder, rest on the top shoulders formed by the ribs 9 and 8, whlle the ribs 25 and 26 engage respectively on the bottom shoulder formed by the rib 8 1n the matrix-holder and the shoulder 10 formed on 8 and on the other the box. The liners are of the construction n Under the top or head of the box an undercut groove o-r recess 27- is formed, whichextends across from end to end of the box, So that the stereotype mat 28 may be inserted therein when it is placed in position in the box. The end of this mat 28 is pushed up into the groove so that the molten metal cannot run around and flow back of the mat 28, and the mat thus seals theupper end of the box against the escape of molten metal. Thetwo open sides of the box are closed by liners 29, as is also the bottom of shown in Fig. 4 and are formed with grooved edges 30, 30, so that they may be used interchangeably, the grooves providing, as shown in Fig. 4:, recesses or undercuts in which the edges of the mat are placed.

The upper edge of the cover or plate 19 1S molten metal and this opening is formed by cutting out or grooving the end of the cover, as at 31, so that the cover or plate 19, in conjunction with the head of the box, forms an inlet for the molten metal.

The plate 20 of the box ispreferably formed with air escape. openings 32 to permit'the escape of the air as the metal is flowed into the box, thereby preventing the formation of air pockets behind the mat 28 and permitting the mat to lie fiat against the inside face of the plate 20.

In operation, the casting box is placed in position when the elevator 11, and with it the matrix-holder, is in a raised position. This box is slid in position in substantially the same manner as a matrix is slid in posi tion on the elevator. The elevator then is allowed to drop down until the opening 31 alines with the mold 2 in the mold-carrying disk 3. Normally-this mold 2 mold 'for the matrix, but when the mold box l8-is placed in position this mold 2 becomes really a'noz'zle or, passage for the molten 1 metal, which is forced out of the metal pot Y and clearer stereotype 5 by the usual pumping action used in linotype machines through the mold 2 and into the opening 31 of the mold box. Due to the fact that the metal is pumped or forced into the box, it quickly flows to all. parts of 55 the box and is forced against the face of the mat before it has had tunity to congeal, so that a much is produced in this manner than has heretofore been possible by the ordinary methods of stereotype making.

In Fig. 5 I have illustrated 'a modified formof the boxv wherein thehead, instead of being formed in one piece, as illustrated in the structure shown Fig. 2, has a secprovided with an inlet opening for theprovides a chineyof a c the slightest opporsharper spaced plates,

tion thereof formed on each the meeting faces of the plates being beveled, as at 33, and the inlet for the metal being in the form of a slot 3 1 through the plate 19.

In using the box as above described in connection with the linotype machine, before.

inserting the box in position the box cover is swung open, as illustrated in Fig. 5, and the mat is laid against the inner face of the plate 20, the upper edge being inserted in the groove 27. Two of the liners 29, 29 are then placed in position at the ends of the box and a bottom liner is placed inits position at the bottom of the box, all of the liners having their grooved edges extending over the ends or edges of the mat. The box cover is now closed and after being warmedrs'ufficiently to prevent chilling. the molten metal too quickly, the box is placed in the elevator, as above described and the stereotype cast.

Having thus described my invention what I claim as new andjde'sire to secure by Letters Patent, is

The combination with a linotype metal pot, of a linotype elevator, a matrix-holder for said elevator, and a.molten metal container independent of thelinotype mold for 0 receiving a stereotype mat supported by said elevator and arranged to be moved into a position to receive-the molten metal' from said metal pot.
